After I remove the droppings and insulation that I can realistically remove manually, it's time to fog. There's no way to manually remove all rat droppings, and of course one cannot remove urine and fur grease. Some of the droppings are down walls. Many are basically embedded in insulation.
Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Through Telnet, an administrator or another user can access someone else's computer remotely.
The Telnet application protocols call the terminal emulator a Telnet client and the device that listens for commands and replies to them a Telnet server. Telnet is a TCP-based application layer protocol that uses port 23. To be able of using Telnet, the user must install Telnet client software onto computer.
